Red flags, green flags, and how to read 'transformations'
Judge a trainer by process, not photos: a good one assesses you first, writes a programme, tracks progress in numbers and puts terms in writing. Pressure to buy big packages, supplement sales and crash diets are the clearest warning signs.

How to read before-and-after photos
Transformation photos are the most persuasive and least reliable evidence a trainer can show. Before you trust one, look for:
- Changes other than the body: lighting, posture, tan, a "pump" from training just before the photo, camera angle or distance. All of these change how a body looks in minutes.
- Time frame and starting point. "12 weeks" means little if the client was a former athlete returning to training.
- Selection. You only see the successes. Ask how many clients they train and what a typical result is.
- Ownership. Some photos are reused from other coaches or the internet. A reverse image search takes 30 seconds.
Instagram followers and reviews
- Follower counts measure marketing skill. Followers can be bought, and they say nothing about coaching.
- On Google Maps, look at the number of reviews and how recent they are, not just the star rating. A 5.0 from 12 reviews tells you less than a 4.7 from 300.
- Read the text. Useful reviews mention specifics: injuries handled, how progress was tracked, punctuality.
Guarantees and challenges
Money-back guarantees and "8-week challenges" can be genuine, but read the conditions. They often require attending a minimum number of sessions, following a diet log, and submitting weekly photos. Ask for the terms in writing before you buy.
